Potential Transformers
Osborne Potential Transformers (PT’s) are used to reduce higher system voltages to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when potential transformers are to be used for power measuring applications.

Solid State Active Synchro Control Differential Transmitter
Computer Conversions Corporation
The input is transformer isolated and accuracy applies over the operating temperature range and with +/-10% input amplitude and frequency variations. The operational amplifier outputs are not transformer isolated, and can be driven into external power amplifiers and Scott "T" transformers for 3 wire synchro outputs. A typical application of this series is in a conventional positioning servo system as a complex error processor. The use of the solid state CDX makes possible the design of servo systems that can be digitally programmed by direct computer input to the digital input of the SCDX.
